Scientists at the University kertina in Australia found that the volcanic eruption that was observed by prehistoric people, actually happened on 245 thousand years later than believed the majority of researchers. Thus, an eyewitness of the disaster had to be modern humans and not Neanderthals. About it reported in a press release on Phys.org.
Experts have determined the age of the traces left by human ancestors in a layer of ashes, formed during the eruption of the volcano Cascallar (Çakallar) in the West of modern Turkey thousands of years ago. To do this, they conducted the analysis of samples of fly ash using two different methods of Dating cosmogenic radiogenic helium and chlorine. The first one allows to determine the age of igneous zircon grains in igneous rocks, and the second the residence time of ash on the surface.
Initially it was assumed that the tracks belonged to the Neanderthals of the Pleistocene epoch, however, the new data showed that the prints are much younger. They belonged to modern humans who lived 4,7 thousand years ago, in the bronze age.
According to experts, people watched the volcano from a safe distance, when its activity is already very weak. The same Homo sapiens, most likely, have left cave paintings, made near the place where the footprints were discovered.
